I think it is too much of a coincidence that so many people are getting bad WUs. I wound up nuking my entire F@H GPU2 folder and reinstalling. Seems to have been good for the last couple of days now. If you are having a lot of trouble, you may want to give that a shot

No issues for me overnight other than the server communication ones, and I just noticed a fairly big update so I suspect they've got some of those problems resolved.

One of the things I've noticed is that my temps seem to be fairly low. Maybe they did something to the drivers in an attempt to resolve the complaints about high temps on 353 WUs and that foobared something else?
